Individual profile asymmetry at twins and EEG spectral characteristics at performance of the arithmetic account and verbally-associative activity
Abstract
In work the purpose of performance of an estimation of the contribution a genotype environmental factors in interindividual variability of profile asymmetry, and also experimental studying EEG-korrelats of verbal intelligence (on an example of performance of verbally-associative activity and the arithmetic account) at twins with various features of individual profile asymmetry was put. The estimation of heritability of type of functional asymmetry has made 0,26, thus the essential contribution in phenotypic variability of the given indicator is brought by the individual environment (e² = 0,74). It is revealed, that degree of expressiveness at examinees of asymmetry of touch and motor and mental functions (a profile of lateral organizations) influences capacity of biopotentials at performance of arithmetic operations of mainly right hemisphere.
